I not only agree with everythig you wrote about BVS, but there's also the fact that it ultimately fels like it was way too much and way too soon for some on the moments in the film. For example (and this is kid of a Spoiler and I apologize for it), the death of Superman... That's a moment that was so transcending and shocking, that it shifted the way comicbooks were made... And it was wasted on a Superman that we only met for 1.5 movies (the .5 being this one). And Jesse Eisenberg (Michael Cera 2.0) was a mess as Lex. I think that this film would've had more of an impact if it was done years later, when real frustation between Bruce and Clark actually existed. It's a shame.
